Hello

 

I am a trying to establish a correlation between penetration and normalizes stress in my Ansys model. How can i make this graph on   Ansys. Moreover I need some information on how to make correlational  graphs between different parameters.

This is the correlation i am looking for

Please show us the geometry of your model, identify the faces that are in contact, labeled Target and Contact. Show the Contact Details panel so we can see all the settings you have.

This graph shows two contact formulations: Lagrange and Penalty. Are you only interested in Penalty?  If so, why don't you use Lagrange?

What are you going to normalize stress with?

Thanks for your quick response.

The model is axisymmetric.

 

I just need to show how the penetration effects the contact stresses. The graph suggest as the penetration increase the accuracy of the results decreases. I have used interference pressure as a normalizing factor. I also have the possibility to change the penetration value and get the stress level at each penetration value but its a time consuming process. Is there a way to get this kind of correlation directly from Ansys. i am using augmented langrange method.

It seems you will have to manually create each data point you want on the graph. The penetration value does not support Parameters.
